Die Art stclle ich in die Sektion Oxysepaliiin, da kein einziges Merkmal sic davon 

 trennt. Nur die Farbung, besonders das rote Labellum, ist fur die Sektion ungewohnlicli. In 

 dieser Hinsicht ist die Art aber variabel, denn bei den 3 Fxemplaren, die ich lebend unter- 

 sucht habe, waren niclit 2 cinandcr ahnlicli.
